SN EN 12101-2:2017 is a European standard published by CEN that establishes the requirements and testing procedures for natural smoke and heat exhaust ventilators (NSHEVs) used in smoke and heat control systems within buildings.

Purpose and objectives

The primary aim of the EN 12101-2:2017 standard is to define the performance and reliability requirements for natural smoke and heat exhaust ventilators. This ensures that these systems effectively manage smoke and heat in the event of a fire, enhancing safety for occupants and facilitating fire and rescue operations. The standard outlines testing methodologies to verify compliance with performance criteria, ensuring that ventilators can respond promptly during emergencies. Overall, it promotes a uniform approach to smoke control in buildings across Europe, supporting fire safety regulations.

Scope: who must comply

The EN 12101-2:2017 standard is applicable to manufacturers, designers, and operators of natural smoke and heat exhaust ventilators used in various building types, including commercial, residential, and industrial facilities. Compliance is crucial for stakeholders involved in construction, fire safety engineering, and regulatory bodies. Organizations in the Environment, Health & Safety (EHS) sector must ensure that their smoke control systems meet these standards to protect lives and property during fire incidents. Companies implementing these systems must also ensure they are trained in the operational guidelines dictated by the standard.

How SN EN 12101-2:2017 relates to other standards

The EN 12101-2:2017 standard is closely related to several other fire safety standards:

• EN 12101-1: This standard complements EN 12101-2 by specifying the performance requirements for powered smoke and heat exhaust ventilators.
• EN 54: A series of standards focused on fire detection and alarm systems, relevant for integrating smoke control systems.
• ISO 7240: This standard outlines the general requirements for fire detection and alarm systems, providing a framework for compatibility with smoke control measures.

Revision history and current status

The EN 12101-2 was first published in 2017 by the European Committee for Standardization (CEN). This current revision, designated as EN 12101-2:2017, includes updates to testing methodologies and performance requirements based on evolving fire safety practices. The standard is currently active and remains a critical reference for compliance and safety in smoke and heat control systems in buildings.
